debugging=runs fine normally=fails

[Jarwulf]

I have a java program that seems to work okay when I'm debugging it or running it from the Eclipse IDE. But when I export it into a jar file and run it through a jnlp it hangs at a certain step.

I'm not exactly sure but I think the problem might be a step when I'm converting a file into a text file.

private File INPUT;
	private JTextArea innerTextArea;

	    protected boolean rangeArgsProvided = false;
    
     Converter(File INPUT, JTextArea innerTextArea) { 
         //initialize 
    	 this.INPUT = INPUT;
         this.innerTextArea = innerTextArea;

     }
    
@Override
public File doInBackground() {//replaces doWork
  	File convertedBAM = new File("convertedFile.txt");
	int convertstepcounter=0, convertstepcounter2=0;

I'm not specifying any specific location to get or put the file convertedFile.txt in. Its just a variable that will take the converted information and then pass on in a later step and not be used anymore. Is there a possible problem with this or is the hanging likely due to something else?



PS the jar runs from the Local Settings/Temp Folder in windows. Someone else made it that way.

It's probably a security manager issue, check out this article http://www.techrepublic.com/article/...andbox/5035300

I signed my jars and they've run before...

It 'crashes' as shown below...I put in text statements to pinpoint the position. Can't dig deeper without a lot of extra trouble because doing so would be going into a jar library file.

INPUT is a file chosen by the user using a file browser.

selectedFile = jfileChooser.getSelectedFile();

final FileConversion task = new FileConversion(selectedFile, txtArea);

//Conversion Function

FileConversion(File INPUT, JTextArea innerTextArea) { 
         //initialize 
    	 this.INPUT = INPUT;
         this.innerTextArea = innerTextArea;

     }

@Override
public File doInBackground() {
  	File convertedFile = new File("convertedFile.txt");
	int convertstepcounter=0, convertstepcounter2=0;
	
publish( 1 );
	IoUtil.assertFileIsReadable(INPUT);//crashes here
publish( 2 );
    final SAMFileReader reader = new SAMFileReader(INPUT);//or here if above line is disabled. 
publish ( 3 );

I also set all permission in the jnlp file and it doesn't help

It could be throwing an exception that you're not aware of. You could try putting throw new Exception("see if I can see this"); after publish( 1 ). If you don't see that exception then the problem is that you're not setup so that you can see exceptions when thrown from that piece of code.

...thinking about it, that might not help. Assuming your 'publish' method simply wraps System.out.println. Why not just post an SSCCE?
